Too soon for a pacifier?

Rayanna • Mom to Lexa💖

My 9 day old just nursed for 2 hours. I think she’s cluster feeding. She’s still rooting & fussing like she’s hungry. But she’s spitting up any more food she takes down. Could she be sucking to soothe? Is it too soon for a pacifier? FTM so I’m lost with what all her signs mean.
